Anchored Walls techs, Zach and Kyle, came ready to work!!! They added 9 anchors to 2 of my basement walls to stabilize them. Those 2 men worked hard! I have attached 2 pictures, the first shows shovels over the holes so no one would fall in, and the finished yard. You cannot tell where the holes had been. Both men also added waterproofing to my basement floor. If Zach and Kyle are an example of what to expect when you hire Anchored Walls, then the company gets 5 stars from me. Great work Zach and Kyle !!! * * * * *

Lack of clean drop cloth to cover for the floors was the only problem. Every thing was great.

An addition at the rear of our house settled due to inadequate concrete footings. Anchored walls came and installed metal rods 12 to 15 feet deep in the ground to level and stabilize the room. Other contractors' approach was way more intrusive - removing windows and flooring to get access. Anchored Walls did all the work from outside.

The crew arrived at about 8:00 a.m. to stabilize my garage wall, which they thought would take about a half day. They ran into unexpected problems under my garage floor and although it was extremely warm, they continued and finished the job at 8 p.m. Even with that they had cleaned up before they left. They did a great job and I appreciated that they were willing to finish as I had arranged for another crew to come to build a deck in that area the next day. That is dedication. Thank you Anchored Walls! K.S.

Frequently Asked Questions

How do I know if my crawl space needs repair?

Look for signs like sagging subflooring, musty smells, mold growth, high humidity, standing water, or visible rot on floor joists and beams. These often show up first in closets or laundry rooms above the crawl space. All of these issues point to possible structural or moisture problems below.

Why is there mold in my crawl space?

Mold is a result of excessive moisture in the crawl space of your home. It’s very important that you take care of a moldy crawl space problem as soon as you notice that something is wrong. If left untreated, mold can cause a number of problems for the structural integrity of your home, as well as your family’s health. If you don’t repair your foundation, water will eventually seep in. This causes an assortment of additional problems for the structural integrity of your home.

What causes crawl space moisture?

Crawl space moisture comes from water seepage, improper yard drainage systems, soil settlement and condensation. Regardless of whether your crawl space is dirt, concrete, vented or unconditioned, these lower areas underneath the home tend to endure the most damage due to the many changes in weather conditions, high temperatures and humidity levels. Humidity and moisture easily travel through your crawl space and can begin to infiltrate the structure of your home.Damp or wet crawl spaces are perfect homes for insects, rodents and other critters. This area underneath your home can be extremely unhealthy, destructive and dangerous. Your wet crawl space can also act as a breeding ground for mold and mildew growth. Mold spreads easily throughout your home when it begins in your crawl space. Mold, as well as wood rot, can negatively affect your home’s indoor air quality. That’s why it’s important to take care of crawl space moisture problems as soon as you notice them.

What will happen if I don't get rid of basement moisture?

If you don’t have a basement waterproofing system installed at your home, the moisture that collects will eventually begin to cause your basement walls and floors to deteriorate. Also, excessive basement moisture can lead to the growth of mold and mildew, which is unsafe for your family to be breath

Why does my home have a wet basement?

Basement moisture is usually caused from cracks along the foundation or an improper drainage system. Foundation cracks act as an entry way for water. Water always seeks the path of least resistance, and this means that water is very likely to enter through these foundation cracks.If left untreated, basement moisture can begin causing damage to both your basement walls and your basement floor.
